A little after a month into his presidency, President Donald Trump delivered his first address to a joint session of Congress on Tuesday evening, sharing his administration's vision for America. Many responded to the speech on social media, including Sen. Bernie Sanders, who tweeted after Trump's speech, criticizing the President for failing to mention what he believes are several crucial details.

Sanders, the junior Senator from the state of Vermont, has long been a critic of Trump and his policies, both throughout his campaign and the duration of his presidency. Following Trump's address to Congress, Sanders heavily critiqued Trump on Twitter for failing to address aspects of several issues that he believes profoundly affect the country, including healthcare, income inequality, and climate change, among others.

Sanders also used both Twitter and Facebook Live as platforms to encourage people to keep standing up for their rights and to make their voices heard through various acts of advocacy and protest in which Americans have been engaging since the beginning of Trump's presidency. These methods include calling elected officials, showing up to Republican town hall meetings, and organizing large demonstrations, among others.

Sanders concluded his Facebook Live address as well as his series of tweets with a fitting message of solidarity to his fellow Americans, imploring, "Those of you who haven't taken action yet: we need your voices, we need your action. Only together, when millions of people stand up and fight ... can we create the political revolution that will turn this country around."

Overall, Sanders' tweets and Facebook Live address indicate that he will continue to play a leading role in holding Trump accountable for his actions and in protecting the interests and rights of all Americans.
